I saw some posts a year ago about some products that can be used instead of teak oil that lasted longer than traditional oil. I searched and couldn't find them. I like the look of teak but would rather not have to think about oiling the swim platform every 2-4 weeks.

I pulled the trigger on teakguard. Their website seemed to make a convincing argument for using non-organic oils and they claim once a year application will get the job done. I will found out this year if that is hype or not.

Edit - I have used the sarbrite oils and know that stuff will start greying in a month or so.
